cURL request with valid GraphQL query fails with "Problem processing request"

The following GraphQL query works as expected for me:

read -r -d '' QUERY << EOF
{
  "query": "query variables { variables(projectId: \"XXX\", environmentId: \"XXX\", serviceId: \"XXX\")}"
}
EOF

curl -s -X POST -H "Content-Type: application/json" -H "Authorization: Bearer $API_TOKEN" --data "$QUERY" $RAILWAY_API_ENDPOINT

read -r -d '' QUERY << EOF
{
  "query": "query variables { variables(projectId: \"XXX\", environmentId: \"XXX\", serviceId: \"XXX\")}"
}
EOF

curl -s -X POST -H "Content-Type: application/json" -H "Authorization: Bearer $API_TOKEN" --data "$QUERY" $RAILWAY_API_ENDPOINT

However, the following deployments query returns: {"errors":[{"message":"Problem processing request"}]}.

read -r -d '' QUERY << EOF
{
  "query": "query deployments { deployments(first: 1, input: { projectId: \"XXX\", environmentId: \"XXX\", serviceId: \"XXX\" }) { edges { node { id, staticUrl }}}"
}
EOF

curl -s -X POST -H "Content-Type: application/json" -H "Authorization: Bearer $API_TOKEN" --data "$QUERY" $RAILWAY_API_ENDPOINT

read -r -d '' QUERY << EOF
{
  "query": "query deployments { deployments(first: 1, input: { projectId: \"XXX\", environmentId: \"XXX\", serviceId: \"XXX\" }) { edges { node { id, staticUrl }}}"
}
EOF

curl -s -X POST -H "Content-Type: application/json" -H "Authorization: Bearer $API_TOKEN" --data "$QUERY" $RAILWAY_API_ENDPOINT

The deployments query matches an example from the docs. When I run the deployments query in the Railway GraphQL playground, it works as expected. In all three cases I've triple checked that I'm using the same auth token and project/environment/service IDs. What could cause the issue with my deployments query? Thanks in advance. ❤️

I'm gonna guess that it's something to do with how you're piping the query into curl, have you tried passing the query in with the --data flag like the curl example shows? https://docs.railway.app/reference/public-api#authentication

@Brody Thanks for the reply. I am using the --data flag in the example I gave above. But yes, I get the same "Problem processing request" error if I pass the query in like this: curl -s -X POST -H "Content-Type: application/json" -H "Authorization: Bearer $API_TOKEN" --data '{"query": "query deployments { deployments(first: 1, input: { projectId: "XXX", environmentId: "XXX", serviceId: "XXX" }) { edges { node { id, staticUrl }}}"} I find it particularly strange that both of the following are true: 1. The first query in my OP, the variables query, works as expected. This suggests that the way I'm piping the query into the cURL request is ok. It also confirms that my project/service/environment IDs are valid. 2. The second query works as expected in the GraphQL playground (with the same project/service/environment IDs). This suggests that my query is valid. The only structural difference I can see between the two queries is the { edges { node { id, staticUrl }} part in the second query. But I can't see a formatting error there. Ohhh wow I'm sorry. There should have been four curly braces here staticUrl }}}, not three. 🤦‍♂️ @Brody Thank you again for your reply here. I had looked at this for an hour or so before resorting to Discord. Happy New Year.

no worries, happy new year to you too, and for anyone in the future who may come across this thread, here is the complete query and variables

query deployments($first: Int, $input: DeploymentListInput!) { 
    deployments(first: $first, input: $input) {
        edges {
            node {
                id,
                staticUrl
            }
        }
    }
}

query deployments($first: Int, $input: DeploymentListInput!) { 
    deployments(first: $first, input: $input) {
        edges {
            node {
                id,
                staticUrl
            }
        }
    }
}

{
  "first": 1,
  "input": {
      "projectId": "",
      "environmentId": "",
      "serviceId": ""
  }
}

{
  "first": 1,
  "input": {
      "projectId": "",
      "environmentId": "",
      "serviceId": ""
  }
}
